COCOA POLYPHENOLS HEALTH EFFECTS – A RECAP
“Are polyphenols the only important constituent of cocoa?” No cocoa contains carbohydrates, fats, proteins, fiber, vitamins, minerals, methylxanthines and polyphenols. This is why cocoa is regarded as a functional food- provides health benefits beyond basic nutrition. Most of the health effects of cocoa-rich chocolate are due to the high content of nutritional polyphenols. In the last thirty years, polyphenols have attracted much interest owing to their antioxidant capacity (free radical scavenging and metal chelating ability) and their beneficial implications in human health, such as in the treatment and prevention of cancer and cardiovascular disease. Hence, cocoa has the health effects generally ascribed to polyphenol consumption.
Cocoa seeds contain many bioactive compounds including high levels of polyphenols (12–18% of dry weight) as well as fatty acids, vitamins, minerals, fiber, and several methylxanthine alkaloids(4% of dry weight), which are psychoactive dopaminergic substances such as caffeine, theobromine, theophylline, phenylethylamine, and paraxanthine.(Massaro et al. “Effect of Cocoa Products and Its Polyphenolic Constituents on Exercise Performance and Exercise-Induced Muscle Damage and Inflammation: A Review of Clinical Trials.” Nutrients 2019, 11, 1471; doi:10.3390/nu11071471). The compounds that show a significant correlation with the cardiometabolic health effects belong to the polyphenol class. Chemical data for dry seeds in the literature give a range of 6-18% of polyphenols, mainly composed of flavanols.
For many years, chocolate was consumed purely for pleasure, but in the last 20 years researches have shown that polyphenol-rich cocoa (dark chocolate with minimum 70% cocoa solids) and natural cocoa powder have beneficial effect on human health due to high content of polyphenols. Polyphenols are large and heterogeneous group of biologically active secondary metabolites in plants, where they act as cell wall support materials, colourful attractants for birds and insects, and defence mechanisms under different environmental stress conditions (wounding, infection, excessive light, or UV irradiation.
The most important food sources of polyphenols are vegetables and fruits, green and black tea, red wine, coffee, cocoa, olives, and some herbs and spices, as well as nuts and algae. But on weight basis cocoa is the richest source of polyphenols. Many researches have shown that polyphenols and/or polyphenol-rich foods have an important role in health preservation due to antioxidant properties. The antioxidant activity of cocoa was shown to be correlated with their polyphenol content.
Polyphenols can act as proton donor-scavenging radicals, inhibitors of enzymes that increase oxidative stress, chelate metals, bind carbohydrates, and proteins. These properties enable them to act as anticarcinogenic, anti-inflammatory, antihepatotoxic, antibacterial, antiviral, and antiallergenic compounds. This is supported by research of Hollenberg et al. who established relationship between high consumption of cocoa beverages and very low blood pressure levels, reduced frequency of myocardial infarction, stroke, diabetes mellitus, and cancer in Kuna Indians residing in archipelago on the Caribbean Coast of Panama. These health benefits were not seen in Kuna Indians residing on Mainland of Panama.
The fat in cocoa in the main is made up of oleic acid, palmitic acid, and stearic acid. Cocoa is also rich in minerals: potassium, phosphorus, copper, iron, zinc, and magnesium.
Polyphenols abundant in cocoa and dark chocolate, activate endothelial nitric oxide (NO) synthase; that leads to generation of NO,, which lowers blood pressure by promoting vasodilation. Indeed, following the consumption of polyphenol-rich, effects include improvement of the pulse wave speed and of the atherosclerotic score index, with parietal relaxation of large arteries and dilation of small and medium-sized peripheral arteries. . Once released, NO also activates the prostacyclin synthesis pathway, which acts as a vasodilator in synergy with NO, thereby contributing to thrombosis protection. Further, the anti-inflammatory and vasoprotective properties of prostacyclin are enhanced by its ability to reduce plasma leukotrienes (inflammatory mediators).
Cocoa plays also a role in treating cerebral conditions, such as stroke; in fact, cocoa intake is associated with increased cerebral blood flow. Polyphenol-rich cocoa has antiplatelet effects and thus of benefit in infarctive stroke treatment or prevention. Thus, daily polyphenol-rich consumption may reduce the likelihood of a stroke attack.
Cocoa and flavonols improve glucose homeostasis by slowing carbohydrate digestion and absorption in the gu. Indeed, cocoa extracts and procyanidins dose-dependently inhibit pancreatic α-amylase, pancreatic lipase, and secreted phospholipase A2. Cocoa and its flavonols improve insulin sensitivity by regulating glucose transport and insulin signaling proteins in insulin-sensitive tissues (liver, adipose tissue, and skeletal muscle).
The observed effects on glucose homeostasis is strongly dependent on the amount of polyphenols. In fact, a single-blind randomized placebo-controlled cross-over study showed, after 4 weeks, showed positive metabolic effects in subjects consuming polyphenol-rich cocoa. Therefore, the daily consumption of small quantities of flavonols from cocoa or chocolate, associated with a dietary intake of flavonoids, would constitute a natural and economic approach to prevent or potentially contribute to the treatment of type 2 diabetes with minimal toxicity and negative side effects.
There is strong interest in the effect of intestinal microbiota on health. Cocoa with its rich fiber content, polyphenol has impacted positively on gut health and in turn on overall metabolic and cardiovascular effects among others.
Studies have shown that cocoa has regulatory properties on the immune cells implicated in both innate (natural) and acquired immunity. Effects worth pursuing and promoting in light of COVID-19.
The polyphenol-rich cocoa acts on the central nervous system (CNS) and neurological functions through the production of NO. Vasodilation and increased cerebral blood flow provide oxygen and glucose to neurons, leading to increased formation of blood vessels in the hippocampus. The polyphenol-dependent antioxidant potential could contribute to the reduction of some neurodegenerative disorders. This inference is based on the fact that age-related cognitive impairment and disorders, such as Alzheimer’s and Parkinson’s diseases, are related to the accumulation of reactive oxygen species in the brain.
The effect of cocoa bioactives on signaling pathways in neurocytes may provide another support for linking it with regulation of brain function. Cocoa flavonols and methylxanthines can activate the cascade pathways of such molecules as rapamycin that play a crucial role in synaptic function, neuronal growth, memory mechanisms, and the pathogenesis of neurodegenerative disorders.
Polyphenol-rich cocoa exerts several effects on human sexuality, mainly acting as an aphrodisiac. Polyphenol-rich cocoa contains three unsaturated N-acylethanolamines, which, acting as cannabinoid mimics, could activate cannabinoid receptors or increase anandamide concentrations. These together with the methylxanthine components produce a transient feeling of well-being.
Until then daily/regularly consume polyphenol-rich cocoa

Today, I focus on the Apostolic Church International in Finland, as I continue with my description of institutions and personalities and their accomplishments as members of the Ghanaian Diaspora in Finland.
The Apostolic Church International, Finland (or, Apostolic International Association Ry) was established in October 9, 2023. The Church in Finland has seen significant strides and accomplishments within the short time that it has been established in Finland, which must be highlighted.
History of the Church in Ghana
The Apostolic Church Ghana originated from the 1904–1905 Welsh revival, officially established in Ghana (then called Gold Coast) in 1935 following connections between a local prayer group in Asamankese (a town in southern Ghana), led by Peter Newman Anim, and the Apostolic Church, UK. There were historical splits in 1939 and 1953, but the Apostolic Church attained autonomy in 1985.
Today, the Church is headquartered in Accra. Last year (2025), it dedicated its new 10-storey headquarters, “The Apostolic Church Tower,” in Frafraha, Adenta West in Accra.
Activities of the Apostolic Church in Finland
The Apostolic Church in Finland conducts church service on Sundays. The service starts at 11a.m. in the morning and closes by 1 p.m. in the afternoon. There are no other activities during other days for now.
The Minister in charge of the church in Finland is also the Area Head of Italy Area. He is Pastor Daniel Kofi Addison who is the new Italy Area Head, and has just been transferred from UK South Area to Italy Area during the just-ended Council Meeting in March this year. Italy Area comprises Italy, which has 13 Assemblies, Germany, one Assembly, and Finland, one Assembly.
Elder Ebenezer Amoaning-Coffie is the Presiding Elder in charge of the Assembly in Finland. A Presiding Elder is responsible for day to day activities of the church (Assembly) and reports to the District Pastor, or in the absence of the District Pastor, reports to the Area Head.
Achievements
The Apostolic Church International, Finland was officially registered under the Finnish Law, guaranteeing freedom of worship and providing legal foundation for future growth. The church service is conducted in both English and Twi.
The church opens its doors to all people of every nation, especially Ghanaians who are in Finland and other African nationals. Now, the membership comprises Ghanaians, Nigerians and Sierra Leoneans.
The Church and the Ghanaian migrant community in Finland
The Apostolic Church in Finland plays a prominent role as a religious group that serves Ghanaian migrants and others in the Finnish society.
Thus, the Apostolic Church is a religious body for Ghanaian migrants in Finland and other nationalities who want to worship with them for diversity and better intercultural and multicultural understanding.
Elder Amoaning-Coffie said that the main and primary aim of the church is to bring people closer to God. “We aim to win souls for Christ. We aim to preach the gospel to the world. By propagating the gospel to the people, we are hopeful that they will turn away from any ungodly ways and be good individuals in the community and in society in general”, he stated.
He said that everything is going well so far. A key challenge, however, is how to get more members especially the youth. As a new Assembly, we are in need of instrumentalists, for example. We pray to God Almighty to help us do His work, the Elder disclosed.
Integration
By its activities, the Apostolic Church is helping to ensure integration of its members well into the Finish society. This is important since social interaction and citizens’ well-being are an important part of the integration process in Finland.
As I mentioned some time ago, the role of migrant associations and groups such as the Apostolic Church acting as bridge-builders for the integration and inclusion of migrants through participation in the decision making process and by acting as a representative voice is highly appreciated in Finland. Thank you!
With Dr Perpetual Crentsil
The landscape of the Ghanaian palate is shifting, and not necessarily for the better. In our bustling urban centres, from the streets of Accra to the suburbs of Kumasi, a quiet culinary revolution is taking place; one where the mortar and pestle are being replaced by the pizza oven and the deep fryer. This transition from traditional staple foods like fufu, banku, akple, kenkey, tuo zaafi, and ampesi toward “continental” dishes is more than just a change in appetite; it is a reflection of a deeper social struggle with identity and prestige.
The illusion of modernity
For many, “stepping out” for a meal has become synonymous with consuming foreign cuisine. There is an unspoken social hierarchy where a bowl of Abunuabunu is relegated to the village category, while burgers, pizzas are branded as prestigious choices. We have reached a stage where we equate foreign with modern and local with primitive.
This perception is a dangerous illusion. Our traditional dishes are marvels of culinary engineering complex, nutrient-dense, and deeply rooted in our history. When we choose a processed foreign import over a meal made from local tubers or fermented maize, we are not just changing our lunch; we are eroding the indigenous knowledge attached to our local ingredients and foods.
We need to turn the consumption of indigenous grains and tubers like millet, sorghum, and plantain into a statement of self-worth and national pride.
The cultural and health erosion
Every time a local dish disappears from a restaurant menu to make room for foreign fast food, we lose a piece of our cultural fabric. Traditional Ghanaian cooking is an art that requires patience and skill. By choosing the convenience of foreign fast food, we are raising a generation that may know the taste of a pepperoni pizza but cannot identify the rich, earthy profile of Prekese or the subtle tang of well-fermented dough dishes like corn porridge, banku, etew, abolo, agidi or kamfa, and kenkey.
Furthermore, we are at the crossroads of a nutrition transition. Replacing high-fiber, indigenous crops with calorie-dense but nutrient-poor foreign fast foods is driving a rise in lifestyle diseases such as obesity, hypertension, diabetes, stroke, cancer, and liver disease. We are trading our longevity for 15-minutes convenience or unhealthy diet.
A call for culinary patriotism
It is time for us to appreciate, preserve, and promote our indigenous foods and culinary traditions. We need to be proud of our local dishes, ingredients and cooking methods, rather than relying heavily on foreign or imported foods. We must stop viewing our local delicacies as low-class and start treating our culinary heritage as the high-end gastronomy it truly is.
True sophistication does not come from imitating Western fast food; it comes from innovation and adding values to our own resources. We see glimpses of this potential in the rise of branded Sobolo and the creative use of gluten-free plantain flour in modern baking of flour-based dishes such as bread, cakes, biscuits and others. This is the path forward. We must elevate our local dishes, making them as accessible, affordable, presentable and trendy as any foreign alternative.
To the hospitality industry: Innovate or stagnate
Our hotels and high-end restaurants must lead the charge. They must stop relegating local dishes to the “traditional corner” of the buffet, and apply the same culinary finesse given to imported dishes to our Fante Fante, apapransa, aborbi tadi, fetritoto, akple, abolo, yakayeke, fufu, ampesi, kokonte, wasawasa, tubani, apapransa, mpotompoto, kelewele, aliha, brukutu, pito, and other local dishes. The industry must enhance customer experiences making eating local dishes the ultimate luxury experience for both tourists and residents alike. We must elevate the presentation of our foods by using modern plating techniques to show that a bowl of light soup can be as visually stunning as a French consommé. We need to reclaim our Ghanaian plate before it is too late.
To the policy makers: Let us encourage buying of local ingredients to promote the local food industry and economy. There should be educational programmes and talks about the nutritional and cultural benefits of local foods so that people understand their value.
We need to encourage serving traditional dishes at school programmes, parties, and celebrations instead of only fast foods,
To the Youth: Let us value and appreciate our traditional dishes instead of always choosing foreign foods. There must be balance in our choice of local and foreign dishes. Confidence in our culture encourages others to respect it too. Our local dishes can also be promoted by sharing pictures, recipes, and videos on platforms such as Instagram, TikTok, and WhatsApp to make them attractive and trendy.
Young citizens must learn from their parents and elders how to prepare local meals to keep the knowledge and cultural relevance alive. Local dishes can be modernised to appeal to younger generations and tourists.
Conclusion
We cannot afford to trade our heritage for foreign cuisines which are gaining grounds across the country at an alarming rate. We must disabuse our minds of the perception that anything foreign or imported is better than those locally made. Our health, economy, and identity are tied to the soil. It is time to stop apologising for our local flavours and start celebrating them. It is possible to embrace modernity without losing ourselves and our cultural identity. Let us make the Ghanaian kitchen the heart of our modern identity once again.
